Wait.. where is everyone going? This is interesting stuff.... Come back!!!!
I took two classes of formal logic, but having not used it much in almost 20 years, it's fading. The bit I remember is contrapositive (!B -> !A in your examples). However, as much as I do truly find this interesting, the strict logical uses of inverse and reverse don't rule the plain English uses, just as "or" in English is usually XOR in circuits.
